"Yeah." Though yeah, it's probably better that they didn't. (As for the Slayer, Jack doesn't really get the chosen part yet, which is a pity as it's not entirely dissimilar from what happened to him, albeit more deliberate. But he never spoke much to Buffy before she disappeared and his research on vampires was more about vampires than Slayers.)
It's definitely time for another rumble, especially since this time - at last - they don't have to stop just when things get fun. The grin on Jack's face is wide and eager, every nerve tingling, every muscle ready for action.
"Aw, you wound me!" he teases, because he may be no Slayer but he's definitely pretty. And since Spike is so very definitely up for this, he doesn't waste any more time before lunging in with a hard fist to Spike's jaw.
